Mild bar compositions comprising blends of higher melting point
polyalkylene glycol(s) and lower melting point polyalkylene glycol(s)
as processing aids
摘要:
The present invention relates to bar compositions comprising a mixture of higher melting point and lower molecular weight (100 to about 1400) lower melting point polyalkylene glycol(s) in which use of the lower molecular weight polyalkylene glycol or glycols allows enhanced rates of extrusion from the plodder.
